摘要
本文介绍了由AT89C52单片机,nrf905无线收发模块,DS18B20温度传感器组成的温度测量系统,并对其硬件组成和软件设计方法做了详细的解释和说明。AT89C52按顺序的采集各点温度传感器DS18B20的数据信号,经过一轮的数据收集和处理之后,数据通过无线发射模块NRF905发射出去。另一边的NRF905模块接收数据,与其相连的单片机处理数据后,通过按键在数码管上显示相应的温度值。AT89C52通过模拟SPI与NRF905通信。该系统主要特点是采用nrf905无线收发模块发射和接收数据,整个系统设计简单,实用方便,具有较高的工程应用价值。
This paper introduces the temperature measurement system based on AT89C52 microcontroller,nrf905 wireless transceiver module,DS18B20 temperature sensor and its hardware and software designing has detailed explanation and instruction.AT89C52 collects data on DS18B20 signal orderly;after a round of data collection and processing,the data transmits through the NRF905 module.The other side of the NRF905 module receives data,and the microcontroller processing data which connected with NRF905.The corresponding temperature is displayed by the button on LED.AT89C52 communicates with NRF905 by simulating SPI.The main characteristics of this system is used the nrf905 wireless transceiver modules to transmit and receive data.The system is easy and convenient,valuable in application of project.
